220V direct contact means closing circuit

Description: BKQ series automatic parallel controllers are specifically designed for small hydropower automation devices operating in parallel, with a capacity of 3200 kW and below, for both high and low pressure turbines. These controllers automatically adjust based on the generator and grid setting conditions. They can also be utilized in thermal power or diesel generator sets for automatic parallel operation. The circuit includes a 2ZOV direct means contactor closing circuit as illustrated in Figure 7-7.

The BKQ series automatic parallel controllers facilitate the integration of multiple power generation sources, ensuring that small hydropower systems can operate efficiently alongside other types of generators. These controllers are equipped with advanced sensing and control algorithms that monitor the operational parameters of the generators and the electrical grid. This enables them to synchronize the output voltage, frequency, and phase angle, which is critical for maintaining system stability and reliability.

The operation of the BKQ controllers involves several key components. The primary component is the microcontroller, which processes input data from current and voltage sensors to make real-time adjustments. The controller is designed to handle various operational scenarios, including load sharing between generators and managing the transition between grid-connected and islanded modes.

The 2ZOV direct means contactor closing circuit plays a crucial role in the control system. This circuit is responsible for engaging and disengaging the generator from the grid. When the system detects that the grid is stable and the generator parameters are within acceptable limits, the contactor closes, allowing power to flow. Conversely, if any discrepancies arise, the contactor will open to protect the generator and the grid from potential damage.

Moreover, the BKQ controllers feature user-friendly interfaces that allow operators to configure settings based on specific operational requirements. These settings include generator capacity, grid conditions, and operational priorities. The controllers are designed to be robust and reliable, ensuring consistent performance even under varying environmental conditions.

In summary, the BKQ series automatic parallel controllers represent an essential component in the automation of small hydropower systems, providing seamless integration with other power generation technologies while ensuring operational efficiency and grid stability. BKQ series automatic parallel controllers are designed specifically for small hydropower automation devices in parallel for a capacity of 3200kW and below the high or low press ure turbine. It automatically according to the generator and the grid setting conditions of people, can also be used in thermal power or diesel generator sets automatic parallel.
